Yes, if you are a student, you can simply download the latest version of Inventor Professional 2010 (not any cracked version but an official license) from the Autodesk Student portal – students.autodesk.com.

This web offers not only Inventor but almost any Autodesk software for free. The only condition is to prove to be a student (have a university e-mail account or be invited from a school representative). I have not tested it myself (and my children are too small fo this) but it seems to work (as I have been told). It is good for technical students to have the latest versions of leading CAD software in their hands. It will be also easier for them to use the respective software in their first job.

In the United States, Autodesk now gives free licenses also to the unemployed designers. I don’t think the same program is available here in Italy (yet).
